Haha! That is so cool. My brother actually has a medal in that sport. Not a big competition, but still. I think I'll have to put this on my bucket list: Watch my brother and Clark Gregg fight in a BJJ competition.

Life imitating art or vice-versa? That's pretty awesome. I count that as two Whedon actors who are already proficient or are studying martial arts (Tahmoh, Muay Thai). I also always wonder why people choose the martial art they study.

Ming Na-Wen looked pretty authentic doing Tai-Chi. I know I remember reading that SMG had studied martial arts before getting the role as Buffy. I'd taken some Korean Tang Soo Do in college, and her stances in the early episodes looked right for a closed fist style, but that isn't people expect from Hollywood.
